In the balance scale/equation analogy, what should you write in the blank on the right side of the equation in order to balance the scale for the following equation? 2(x + 1) = 2x + ______
(x + 1)
4
x
2
Answers
Answer:
Option D: 2 is the correct answer.
Step-by-step explanation:
Given equation is:
2(x + 1) = 2x + ______
For balancing the equation, the variables and constants must be same on both sides of the equation.
Simplifying 2(x+1) gives us 2x+2
As 2x is already there, we will add 2 with it in the equation.
Hence,
Option D: 2 is the correct answer.
The random variable X has mean 12 and standard deviation 3. The random variable W is defined as W = 7+2X. What are the mean and standard deviation of W?
A. The mean is 24, and the standard deviation is 6.
B. The mean is 24, and the standard deviation is 13.
C. The mean is 31, and the standard deviation is 3.
D. The mean is 31, and the standard deviation is 6.
E. The mean is 31, and the standard deviation is 13.
Answers
Answer: D. The mean is 31, and the standard deviation is 6.
Step-by-step explanation:
Given the data :
X = mean = 12 ; Standard deviation = 3
W = 7 + 2x
Variance of W = 2x
Variance = Standard deviation²
(2x)² = 4x²
Variance
Standard deviation of X = 3
Variance (W) = 4*3² = 4 * 9 = 36
Variance (W) = 36
Standard deviation = sqrt(variance)
Standard deviation = sqrt(36) = 6
Mean ; of x = 12
Mean(W) = 7 + 2(12)
Mean = 7 + 24
Mean = 31

In the diagram below, the three lines intersect in the same point, forming six numbered angles.
Answers
For the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.
Given that, A figure of the intersecting lines is given where 3 lines intersect at the same point.
What is the angle?The angle can be defined as one line inclined over another line.
What is a Line?A line can be defined by the shortest distance between two points is called a line.
Here,
From the figure
∠1 = ∠4
∠2 = ∠5
So,
∠6 = ∠3
Now, from the option, the property hold is m∠1 + m∠3 + m∠5 = 180°. because m∠1 + m∠6 + m∠5 = 180°, or ∠6 = ∠3.
Thus, for the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.

Step-by-step explanation:
If you add up all the angles of a triangle, you get 180°.
So you must add up all the angles.
[tex]27+32+x=180\\\\59+x=180[/tex]
Next you subtract 59 on both sides.
[tex]x=121[/tex]
x should be 121°.

Answers
Answer:
0.288
Step-by-step explanation:
Calculation for what is the probability that exactly 2 of them will be baskets
In order for us to find the probability that exactly 2 of them will be baskets we would have to make use of binomial distribution using Microsoft Excel
P =4 baskets/10 shots=0.4,
x = 2
n = 3 shots
P(2)=BINOMIAL DISTRIBUTION(2,3,0.4,FALSE)
P(2)=0.288
Therefore the probability that exactly 2 of them will be baskets is 0.288
